Non-equilibrium dynamics of stripes in cuprate superconductors

We use the time-dependent Gutzwiller approximation for the single-band Hubbard model to analyze the non-equilibrium dynamics for stripe ground states. In particular, we are interested in the interplay between spin and charge dynamics which is analyzed by quenching the system either in the charge or spin sector. This allows us to investigate the coupled relaxation dynamics as a function of the supplied energy. Further insight is provided by mapping the Gutzwiller dynamics onto a time-dependent Landau approach which lacks the double occupancy contribution to the time-evolution but allows to tune the coupling between spin-and charge degrees of freedom.

In this study, the time-dependent Gutzwiller approximation is used to analyze the non-equilibrium dynamics of the single-band Hubbard model, focusing on the interplay between spin and charge dynamics. By quenching the system in either the charge or spin sector, the coupled relaxation dynamics as a function of supplied energy is investigated. Mapping the Gutzwiller dynamics onto a time-dependent Landau approach provides further insight into tuning the coupling between spin and charge degrees of freedom.
